The pristine blue waters of Shark Bay in Australia were temporarily red as 70 tiger sharks ripped apart a massive humpback whale in a feeding frenzy captured by an eco-tourism cruise’s drone photographer.

Eco Abrolhos, the cruise boat company that published the video, captioned it with this:

“Feeding frenzy at Shark Bay – Tigers having a whale of a time.”

Shark Bay is World Heritage area 500 miles north of Perth and is known for vibrant marine wildlife and eco-tourism.
